Hello, i am new on the forum, i have same problem, both battery full, no remote connection, wifi ok, message on app "remote control low voltage"
Did you find a solution ?
Assuming that you had flown the drone before without issue...... until now.
Assuming also that you know you can fly the drone with your phone instead of the remote control .
If yes, try and see if you can fly the drone that way.
If successful then ..............
RE : both battery ful
If that is true, then the message "remote control low voltage" suggests a faulty remote control.
I have no fix for that, except a suggestion ....... buy a sjrc z5 remote control as replacement.
You can have it from Aliexpress.
